NOTES

  • This subclass covers radar, sonar, lidar or analogous systems specifically designed for geophysical use. Radar, sonar, lidar or analogous systems, or details of such systems, if of a general interest, are also classified in subclass G01S.
  • In this subclass, the following term is used with the meaning indicated:
    • "tags" means arrangements cooperating with a detecting field, e.g. near field, and designed to produce a specific detectable effect; "tags" also means active markers capable of generating a detectable field.
  • In this subclass, the geophysical methods apply both to the earth and to other celestial objects, e.g. planets.
  • Attention is drawn to the Notes following the title of class G01.
